BR-15 and BR-16 are NOT Nikon Official Model Numbers

Since around 2004, I've seen books and websites described as BR-15 and BR-16.
As you know, BR is the model number of Nikon's camera division. The MULTIPHOT system is a product of Nikon's microscope division. It is impossible for Nikon's microscope division to use the model number of the camera division.

That was in April 2021. I asked Mr. Hans Braakhuis from the Netherlands about my question aboout BR-15 and BR-16. Hans-san is a famous Nikon historian. Hans-san gave me a detailed answer right away.

Hi Michio

You're right, not an official name. Just made by the US importer Ehrenreich Photo-Optical Industries (EPOI). I never saw one with the BR- inscription. I think I have the name from list of available goods.

Met vriendelijke groet,

Hans Braakhuis.

Hans-san thank you very much for your kind answer.

Attention

The BR-15 should be written as "BAYONET MOUNT ADAPTER" as correctly defined by Nikon.
The BR-16 should be written as "SCREW MOUNT ADAPTER" as correctly defined by Nikon.

Adapter Types

The Nikon MULTIPHOT system was released in 1968. Production was discontinued in 1995, but sales continued until around the end of 1997. Since it was manufactured and sold for a long time, I believe there have been several improvements and upgrades.

There are also several types of BAYONET MOUNT ADAPTER and SCREW MOUNT ADAPTER.

BR-15 and BR-16 do not exist, but BR-2 does. It later became BR-2A. I bought over 40 BR-2A's. Don't tell anyone, okay?
